Road Closure: A303 — Southampton

Motorists planning to use the A303 near Micheldever should be aware of overnight roadworks scheduled to take place on 11 September 2026, starting at 20:00 and ending at 05:00 the following morning. The works, classified as minor, will be carried out under the underpass on the A303 trunk road, and are being undertaken by Hampshire County Council. Although the disruption is expected to be medium in severity, drivers are advised to plan their journeys in advance and consider using alternative routes to avoid potential delays.

The roadworks are likely to affect drivers travelling between Southampton and other parts of the country, particularly those using the A303 as a main route. Hampshire County Council has planned the works to take place overnight to minimise disruption to traffic, but drivers should still expect some delays, especially during peak hours. It is essential for motorists to check for updates before embarking on their journey and to consider using alternative routes, such as the M3 or M27, to avoid the affected area.

To stay informed about the latest traffic conditions, drivers can use traffic apps or websites, which provide real-time updates on roadworks, congestion, and accidents. Additionally, Hampshire County Council's website may have more information on the roadworks, including diversion routes and expected completion times. Drivers can also tune into local radio stations for traffic updates and advice on the best routes to take.

While the roadworks are expected to be completed by 05:00 on 12 September 2026, drivers should still exercise caution when travelling through the area, as there may be residual delays or lane closures. It is also important to follow any diversion signs or instructions from traffic management personnel to ensure safety and to avoid any further disruption.

Hampshire County Council has apologised for any inconvenience the roadworks may cause and appreciates the cooperation of drivers during this time. The works are necessary to maintain the integrity of the road network and to ensure the safety of all road users.
